My son 7 years old has a pain in feet (ankle-lower side). Six months back we got x-ray adone and had consulted the doctor. He said that this kind of pain is common in growing kids. With some rest, the pain was gone. And he stopped wearing school shoes. But, recently the pain has come back and now we want to know how can this problem be solved. He has to wear school shoes also. Are there any special shoes for this kind of problem ?What care he should take to reduce the pain?
